I own a Roland SPD-20, which although has nice sounds taken from a TD brain they were lacking in punch as I am a rock drummer, so even with the few items in the demo I was impressed by the beefiness.
One other reason I wanted a ROMpler is because I tidy my kit away after use so it's a drag just to hook it up for edits when I can put my 2 octave keyboard controller on my lap and hear on-disk than on-kit.
I have a 6yr old computer and can get down to 3ms latency on my EMU 0404 PCI easily and it sounds good.
I've had a couple of crashes in Sonar 6 LE, but every now and then it doesn't, which I'm okay with. Nice job lads, I'll be buying my copy locally tonight.
